Tridex APM-SG Automated Pointing Machine Surface Grinder
The Tridex APM-SG Automated Pointing Machine Surface Grinder is a fully automated, programmable pointing and material-handling system for producing Menghini, tri-bevel, back-bevel, trocar, diamond, stylet, Franseen, Chiba, Pencil point, and other custom points. Its design is modeled on the same burr-free grinding technology as the Tridex SG-1645 and SG-2060 ECG Grinders and the precision handling of the Tridex PGS-100.
For maximum productivity, the APM-SG incorporates a pallet index table and two PGS-100 fixtures for ECG or two PGS-100A fixtures for abrasive grinding. By loading automatically while grinding, output and productivity increase by nearly 3x for specialty medical needle-pointing applications such as Menghini and Trocar needles. The APM-SG integrates easily into a complete pointing cell with secondary operations such as electropolishing, grit blasting, and laser marking.
For shorter cannulas, the APM-SG cuts and points blanks, then a robot transfers the pointed parts to a single-axis ECG cuto machine, such as the Tridex MCS-12 Single Axis Burr-Free Cuto Machine, for trimming to length.
Product Details
Key Features
- For maximum productivity, the APM-SG incorporates a larger pallet index table accommodating two PGS-100 fixtures for ECG or two PGS-100A fixtures for abrasive grinding.
- Capable of producing Menghini, tri-bevel, back-bevel, trocar, diamond, stylet, Franseen, Chiba, Pencil point, and other custom points.
- Capable of grinding cannula and other parts with hubs.
- Cannula (tubes or wires) remain stationary for point angles and do not tilt.
- Easily integrates into a complete pointing cell with secondary operations, such as electropolishing, grit blasting, and laser marking.
- Double-ended needles can be pointed with additional tooling
- With an additional automation cell, shorter cannulas can be pointed and then automatically transferred to a single-axis ECG cuto machine.
- Precise Flange-mounted electrolytic grinding spindle, with 7.5HP (10kw) direct-drive servo motor
- A moving platen with a servo motor and ballscrew precisely controls cannula rotation.
- Cannulas need no tape for holding the tubes in place.
Additional Features
- Point Geometry changes by rotation, and the wheel position is controlled by CNC.
- Servo ballscrew design for high-precision rotation and repeatability.
- 4 in wide wheel Plunge Grinds all cannulas at once.
- Integrated Servo Drive Wheel Dresser.
- Robust all stainless-steel construction and enclosed design doesn’t corrode, keeping the loading area dry and protected from electrolyte.
- Stainless steel electrolyte tank sealed against mist and leaks.
- Long-life precision rubber clamp pads.
- Pneumatic cylinders for clamping.
- Programmable part setup, no mechanical adjustments.
- Wheel moves in X, Y, and Z axes.
- Standard Mitsubishi M80CNC control with MPG Handwheel.
- Meets CE & ISO 13849 safety standards.
- The standard machine is ECG, and an abrasive version is also available depending on customer requirements.
- The ECG process allows for higher metal removal and long wheel life.
- Based on the proven Tridex SG-2060 platform.
- Machine front opens towards the operator or robot for easier setup and loading; changeovers between diameters and tip profiles take minutes to complete.
- Simpler Automation.
